+# NAME
+
+waybar - upower module
+
+# DESCRIPTION
+
+The *upower* module displays the main battery capacity with all other upower
+compatible devices in the tooltip.
+
+# CONFIGURATION
+
+*icon-size*: ++
+	typeof: integer ++
+	default: 20 ++
+	Defines the size of the icons.
+
+*format*: ++
+	typeof: string ++
+	default: {percentage} ++
+	The text format.
+
+*format-alt*: ++
+	typeof: string ++
+	default: {percentage} {time} ++
+	The text format when toggled.
+
+*hide-if-empty*: ++
+	typeof: bool ++
+	default: true ++
+	Defines visibility of the module if no devices can be found.
+
+*tooltip*: ++
+	typeof: bool ++
+	defualt: true ++
+	Option to disable tooltip on hover.
+
+*tooltip-spacing*: ++
+	typeof: integer ++
+	default: 4 ++
+	Defines the spacing between the tooltip device name and device battery ++
+	status.
+
+*tooltip-padding*: ++
+	typeof: integer ++
+	default: 4 ++
+	Defines the spacing between the tooltip window edge and the tooltip content.
+
+# FORMAT REPLACEMENTS
+
+*{percentage}*: The battery capacity in percentage
+
+*{time}*: An estimated time either until empty or until fully charged ++
+depending on the charging state.
+
+# EXAMPLES
